The Enduring Importance of COBOL in Modern Economy

The video begins with a discussion on the critical importance of the COBOL programming language, which underpins many current financial systems. Despite being 70 years old, COBOL remains essential for banks, insurance companies, and pension funds. The major issue is the dwindling number of developers proficient in this language, with many nearing retirement. This situation is prompting some companies to hire 60-year-old developers on permanent contracts to maintain these vital systems. The guest, a young COBOL expert, explains the history and evolution of the language. COBOL was created at the request of the U.S. Army in the 1950s to standardize computer code. Quickly adopted by banks for its performance in fixed-point calculations, it became indispensable for financial transactions. The first machines using COBOL were mainframes, powerful central computers with magnetic tapes for storage. Developers of the time used punch cards to write their code, a long and complex process. COBOL is known for its readability, using keywords close to natural language, making it accessible even to non-programmers. For example, instead of writing "X = X + 1," one would write "ADD 1 TO X." This feature facilitated code auditing by non-specialists. The first development interfaces were simple monitors without mice, where each line of code had a number to avoid compilation errors. The video also addresses the security of COBOL. Contrary to popular belief, COBOL is very secure due to its centralized architecture and IBM's rigorous security standards. Vulnerabilities are rare and often linked to social engineering rather than technical flaws. One crucial point is the shortage of COBOL developers. Current experts, often aged 55 to 60, possess valuable knowledge. Their retirement poses a serious continuity problem. However, for young developers interested, learning COBOL can be a lucrative and stable opportunity, as COBOL systems are not disappearing anytime soon. In conclusion, the video highlights the enduring importance of COBOL in our modern economy and the challenges associated with its maintenance. It offers a fascinating historical and technical perspective on this often overlooked but essential language.
